Age of the universe

about 13.8 billion years

Age of Universe (Big Bang/Urknall). Perhaps the most important discovery of the Planck observatory was the reception of microwave radiation. The device received light from only 380,000 years after the Big Bang. Using this data we now know that the universe itself is 13.8 billion years old, plus or minus 0.05 billion years – that is more than 100 million years older than was always assumed.
